Lucy 2.5 by Decart

Lucy 2.5 is Decart's real-time world-editing model for transforming live video through text and visual direction. It can swap a character, add or remove an object, alter an attribute, replace a background, change a visual style, or introduce effects while trying to preserve the motion of the original stream. Decart positions the technology for live shopping, advertising, streaming, social platforms, gaming, and other experiences where waiting for an offline render would destroy the interaction. The edit can become part of the broadcast rather than a step performed after recording.

Lucy becomes impressive when a transformation survives movement instead of looking good in a single frame. That opens ideas such as live costumes, audience-controlled streams, virtual try-on, and visually adaptive games. Fine hands, faces, text, occlusion, and fast motion can still expose temporal errors, and public performance figures vary by configuration. High-stakes use therefore needs testing against actual footage before any broad speed or fidelity promise is repeated. The underlying achievement remains substantial: generative editing is becoming fast enough to join the event.
